REGARDING CLAIM OF A GOOD

I RECEIVED A FILA SLIPPER DATED 03-02-2015
AFTER 1 DAY OF USE , COLOUR OF THE SLIPPER STARTED FADING. SO I WENT FOR REFUND. BUT THE COMPANY REFUSED TO CLAIM GIVING THE REASON THAT I DONT HAVE THE PACKET CONTAINING THAT SLIPPER.BUT THE M.R.P IS WRITTEN ON THE SLIPPER ITSELF AND I HAVE THE INVOICE AS WELL. SO I WANT THAT STRICT ACTION MUST BE TAKEN AGAINST THE COMPANY.
